. SPIKE ATTACHMENT FOR SHOES Filed April 29, 1930 Inventor A Ilomey Patented Sept. 15, 1931 UlTED STATES ERNEST JACOB KREBS, OF NEW ORLEANS, LOUISIANA SPIKE ATTACHMENT FOR SHOES Application filed April 29,

This invention relates to an improved spike attachment for shoes, the invention consisting broadly in the provision of a spike resembling a Well known type of base-ball spike and having suitable means associated therewith whereby the spikes may be readily and easily secured to or detached from a shoe, converting a conventional type of walking shoe into a shoe adaptable for use when participating in baseball or similar sports, and also rendering the shoe adaptable for hiking A still further object of the invention is to provide a spike of the character above mentioned, which may be detached at will from the heel of the shoe without injurious effect to the shoe or the heel thereof.

Other objects and advantages of the invention will become apparent during a study of the following description, taken in connection with the accompanying drawings, wherein:

Figure 1 is a rear elevation of a shoe heel illustrating my invention as secured thereto.

Figure 2 is a bottom plan view thereof.

Figure 3 is a perspective view of the heel engaging cleat.

lVith reference more in detail to the drawings, it will be seen that the numeral 5 designates generally my improved spike, the same being somewhat similar to a conventional and well known type of base-ball spikes. The plate-like body portion of the spike being substantially triangular in configuration and provided at each corner thereof with ground engaging spurs or spikes 6.

The plate-like body of the spike is adapted to be disposed flatly against the undersurface of the shoe heel. Extending laterally from opposite sides of the body the same is provided with relatively flat elongated extensions 7 of suitable length as to terminate laterally of the opposite sides of the shoe heel. Slidable on the projections 7 are heel engaging cleats 11. Each of the cleats 11 at their lower ends are provided with a slot 12 for accommodating the extension 7, while at its upper free end the heel engaging cleat is bent inwardly as at 13 for engaging the adjacent sides of the shoe heel.

1930. Serial No. 448,287.

Each of the extensions or projections 7 at their free ends are provided with upstanding apertured lugs 8 having a screw 9 threaded therein. The screw 9 at its outer end is square to facilitate turning of the screw thrpug'h the medium of a suitable key or other too Each of the shoe heel engaging cleats 11 on one face thereof is provided with a depression or recess 14 for accommodating the inner end of the screw whereby upon turning of the screw in one direction the heel engaging cleat is moved inwardly to engage the shoe heel thus securely retaining the entire spike structure in position on the shoe.

From the foregoing then it will be seen that the improved spike may be readily and easily, and at will attached or detached to a shoe heel thus providing a suitable anti-slipping device for the shoe and transforming the usual walking shoe into a shoe adapted for certain exercise as base-ball, hiking or the like.

Even though I have herein shown and described the preferred embodiment of my invention, it is to be understood that the same is susceptible to changes fully comprehended by the spirit of the invention as herein described, and the scope of the appended claim, as for example, the spike may be readily at tached to the sole of the shoe, a mere reduction in size of the cleat 11 being all that is necessary in order that the cleat may securely engage the side edge of the sole in a manner apparent.

Having thus described my invention, what I wish to claim as new is In a device of the class described, a triangular plate having ground engaging members depending therefrom at each corner thereof, said plate having projections extending laterally from the opposite sides thereof, apertured upstanding lugs on the free ends of said extensions, sole engaging cleats slidable on said extensions at the lower portion thereof, and adjusting screws threaded through said lugs and bearing against said cleats for retaining the upper portion of said cleats in engagement with the sole.

In testimony whereof I affix my signature.

ERNEST JACOB KREBS.
